Title: Screening assay for the identification of inhibitors of macrophage migration inhibitory factor
Inventor: BUCALA RICHARD
IPC: A61P29/00
Filed: 1997-02-14
Granted: 2010-06-29
Abstract: There is disclosed assays to identify compounds that inhibit an enzymatic activity of MIF (macrophage migration inhibitory factor). The enzyme activity catalyzes a tautomerization of MIF-substrates, such as D-dopachrome to DHICA. In general, the assay is conducted in vitro by adding, mixing or combining MIF polypeptide and a suitable substrate in the presence or absence of a test compound, and measuring the tautomerization of the substrate. The test compounds that inhibit tautomerization in the assay are identified as MIF inhibitors.

Abstract: A process for forming sodium tungstate using a pyrometallurgical operation is provided. A tungsten containing concentrate (12) together with silica (14) and sodium silicate (16) are introduced into a slagging furnace (18). A higher density tungsten containing phase (20) settles to the bottom of the furnace crucible due to gravity and a less dense slag phase (22) segregates to the upper portion of the furnace crucible. The higher density tungsten phase (20) is introduced into a sparging furnace (24). Gas (26) from the slagging furnace (18) can be subjected to particulate control (28). The recovered particulate matter (30) can be recycled to theslagging furnace (18) and the treated gas (32) can be vented to the atmosphere. A carbon containing gas (34), such as methane, is introduced into the sparging furnace (24). The sparging step results in a crude tungsten carbide product (52) which is subjected to a water leaching step (54). The liquid portion (58) is fed to acrystallizer (60) and the crystals (64) are comminuted (66) in water (68) and subjected to acid leaching (70) with a suitable acid (72). High purity tungsten carbide (78) is then recovered.

Abstract: A rotating anode X-ray target has a matrix structure such as a carbon-carbon matrix and a high Z material imbedded inside this matrix structure. The high Z  material may be a refractory metal with atomic number at least 72, its alloy or carbide and may be imbedded in the matrix either as discrete particles or as a non-discrete layer. Such a target can be made by any of a number of known methods such as chemical vapor deposition and chemical vapor infiltration.  Without a TZM layer or a braze required for holding together an X-ray-producing surface layer and a carbon heat storage material, the target can be made lighter and can be operated at higher temperatures.

Title: Inductive braking in a dual coil speaker driver unit
Inventor: BUTTON DOUGLAS J
IPC: H04R9/02
Filed: 1998-09-22
Granted: 2000-05-09
Abstract: An electro-magnetic loudspeaker, with dual voice coils operating in corresponding magnetic fields in annular gaps between permanent magnet pole pieces, is provided with a single short-circuited braking coil of one or more turns mounted on the voice coil form midway between the two voice coils. The braking coil has minimal effect on normal operation of the loudspeaker, but introduces an inductive braking effect from counter-EMF whenever the voice coil assembly displacement approaches a working limit in either direction, as the braking coil enters a corresponding one of the two magnetized gaps. Thus bidirectional braking/damping is accomplished in a dual coil speaker by the addition of a single braking coil, which could be simply a one turn ring; whereas bidirectional inductive braking in a speaker with a single voice coil requires two such braking coils flanking the voice coil. The single braking/damping coil can be brought out to terminals for connecting it in a loop circuit with an active feedback driver and/or a network of one or more reactive components, for modifying and enhancing the braking/damping action.

Abstract: In a multi-access communication system where a center station dynamically allocates the band of an uplink to subscriber stations, the band of an uplink is flexibly and efficiently allocated when the up-service quality is insured. When requesting a service quality assurance, the subscriber station 30 transmits the service quality request information 210 to the center station 10. The center station 10 transmits the identifier allocation information 310 to the subscriber station 30 to allocate an identifier. When the service priority is high, the center station 10 periodically transmits the reservation transmission permission information 410 and 411 to the subscriber station 3 at the reservation permission transmission intervals 910, thus checking for the presence or absence of reservation information. Waste consumption of the up-band can be suppressed by periodically transmitting the reservation transmission permission information even if subscriber stations issue up-data at irregular intervals. The upper limit value of up-delay amount can be insured by adjusting the transmission period of reservation transmission permission information.

Abstract: There is provided a motion simulator comprising a platform mounted on a base, the platform being mounted by a multi directional swivel connection with first and second motion actuators situated proximate first and second sides of the platform. Each motion actuator comprises a motor, a shaft rotatably driven by the motor and a cam member mounted on the shaft. A roller is mounted on the cam member and is associated with a follower mounted on the platform, the arrangement being such that rotation of the shaft and the cam will cause the roller to move within the follower and cause vertical movement of the platform proximate the follower. The platform can thus move in a vertical plane and also have rotational movement about an axis extending longitudinally of the platform.

Abstract: Le système de télécommunication mobile cellulaire non terrestre étend l'usage de fréquences radioélectriques existantes, d'un système de télécommunication mobile cellulaire affectées pour des communications au sol, à des stations d'abonnés mobiles non terrestres en ajoutant au réseau existant du site cellulaire au sol un chevauchement de cellules non terrestres d'une forme géométrique et d'une position dans l'espace prédéterminées. La polarisation des signaux produite par les éléments d'antenne non terrestres est une polarisation qui est différente, et de préférence pratiquement orthogonale, de la polarisation des signaux hertziens cellulaires générés par les antennes au sol, par exemple une polarisation horizontale, de façon à réduire d'éventuelles interférences avec les signaux hertziens au sol polarisés verticalement. De plus, les signaux de commande échangés entre les stations d'abonnés mobiles non terrestres et le contrôleur du site cellulaire non terrestre sont architecturés de manière à éviter d'éventuelles interférences avec les paires d'émetteurs-récepteurs du site cellulaire au sol. Notamment, les canaux de commande utilisés pour les stations d'abonnés mobiles non terrestres sont sélectionnés de sorte que les signaux de commande émis dans ces canaux ne puissent être reconnus par les stations d'abonnés mobiles et les paires d'émetteurs-récepteurs du site cellulaire au sol, de sorte que, même si les diffusions provenant d'une station d'abonné mobile non terrestre atteignent une station d'abonné mobile ou un récepteur du site cellulaire au sol, celles-ci ne puissent être interprétées et soient rejetées.
